Cylinder kit AIRSAL Tech-Piston 78.5cc 50mm for Piaggio / Derbi D50B0 engine

78.5cc Airsal Tech-Piston cylinder kit. Supplied complete with all components required for assembly, such as seal kit, piston, piston rings, etc.
The 78.5cc Tech-Piston is exactly the same as the 78.5cc Racing in terms of timing and also features the large 2-piece exhaust. The difference is in the compression ratio. The outlet offers sufficient performance potential and the kit is equipped with a very high quality brand name piston (Mahle or Vertex).
These pistons are made of a particularly resistant aluminium alloy and reduce the risk of piston seizure.
The aluminium design of the cylinders and the extremely hard chrome-plated raceway coating ensure significantly better heat dissipation compared to grey cast iron. This makes the cylinders less susceptible to wear and tear and piston jamming due to temperature problems.
The piston crown of the Tech-Piston is crowned and in combination with the special cylinder head leads to very good compression values. The piston is equipped with only one piston ring, reduces friction losses and thus provides the last remaining engine power. MAHLE, the world's largest piston manufacturer, uses a particularly resistant aluminum alloy and further reduces the risk of piston seizure.
Airsal's cylinders are made of aluminium with an extremely hard chrome-plated raceway coating, which has much better heat dissipation than grey cast iron. This makes the cylinders less susceptible to wear and tear and piston jamming due to temperature problems.
Adjustments to the crankcase are not necessary with this cylinder.
Attention: A mounting on mopeds with Euro4 engine (from year of manufacture 2018) is only possible in connection with the thread adapter 38293, because a temperature sensor (4-pole) with M12x1,5mm thread is installed on these models.
